IMPROVMENT IN WELLS.

Specification forming part of Letters Patent N o. 129,314, dated July 16, 1872.

To whom it may concern:

Beit known that I, WILLIAM M. CAMPBELL, of Evanston, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Wells; and I do declare that the following is a true and accurate description thereof, reference being had to the accompan ying drawing and to the letters of reference marked thereon and being apart of this speciication, in which- Figure l is a vertical section, showing the construction of my improved well.y Fig. 2 is a horizontal section. Fig. 3 is an elevation of one of the sections of the lining, and Fig. 4 is a plan of the perforated bottom plate.

Like letters refer to like parts in each gure.

The nature of this invention relates to an improved construction of wells, whereby pure and liltered water will always be supplied to the pump, and quicksand excluded, and which will also prevent the access of vermin to the water. i

The invention consists in curbing or lining the well with cylinders of terra-cotta of less diameter than the well proper, the space between the bottom and sides of the cylinder and those of the well-shaft being lled with coarse gravel, which lters the water flowing into the cylinder at the bottom thereof 5 also in the arrangement for Ventilating the well and excluding vermin.

In the drawing, A represents a well-shaft sunk, of that diameter and to the required depth. At the bottom of the shaft there yis placed a layer of coarse gravel, B, and on this is laid the terra-cotta bottom-plate C, perforated with apertures about one-sixteenth of an inch in diameter and provided with an encircling flange, which receives a terra-cotta cylinder, D,on which is placed another and similar cylinder, and so on until the surface of the ground is reached, the said lining being covered at the top by a terra-cotta cap, E, in the apex of which there is an aperture, through which the suction-tube F passes. The top and bottom edges yof the cylinders are formed with flanged oii'sets, which overlap each other and thereby make a strong joint. rlhe joints above the water-line I cement, while those below it I do not. I fill the annular space between the cylinders and the walls of the well-shaft with coarse gravel until near the surface of the ground, when I surround the cylinder with a iiooring of planks, fitting snugly thereto, on which I rest a wooden-curb, H, having an opening, I, at one side, covered with wire-cloth to prevent the entrance of insects. The earth is then filled up on the flooring to the surrounding level. K is the pump, its llange being being bolted to the cover of the curb, the opening in which should lit the pipe snugly, and which cover should be in two halves to permit of the withdrawal of the suction-tube and its strainer when necessary. G is a perforated sheet-metal case resting on the conical cap E to prevent the entrance of vermin to the well, which may burrow through the curb. The strainer at the lower end of the suctiontube rests upon a terra-cotta plate, L, supported on the plate C by short studs on its under side, so as not to interfere with the flow of water to the strainer. The advantages of this construction over the ordinary brick or stone-Curbed wells are so'evideut that no argument need be made init-s support.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The lining described, consisting of the sections D, the perforated bottom-plate C, and the inclined capE, the parts uniting to entirely inclose the lower end of the pum p-barrel within the lining, as described.

2. The combination,with the inclosin g lining, of the protecting cap G, as described.
